Specification of Letters Patent.

Patented June 20, 1916.

Original application filed May 25, 1911 Serial No. 629,269. Divided andthis application filed October 5, 1912. Serial No. 724,122.

To all whom it may concern: I

Be it known that I, WILLIAM SOBEY, a citizen of the United States, and aresident of Racine, county of Racine, and State of Visconsin, haveinvented certain new and useful Improvements in Plows, of which thefollowing is a full, clear, and exact description.

The improvement relates to plows and more particularly to plows such asare arranged in gangs drawn by traction engines.

The invention seeks to provide an 1mproved manner of mounting the plowbody upon the plow beam by which the p tch of the plow body can bereadily adpisted and which is so arranged that the plow body can bethrown'upwardly and forwardly independently of the main beam thereof incase the plow body strikes an obstructlon and also to facilitate theremoval of the plow bodies from their standards. The present applicationis a division of an earlier appllcation filed by me in the United StatesPatent Office May 25, 1911, Serial No. 629,269.

The invention consists in the features of improvement hereinafter setforth, illustrated in the preferred form in the accompanying drawing andmore particularly pointed out in the appended claims.

In the drawing, Figure 1 is a plan view of the improved plow. Fig. 2 isa view in elevation thereof, showing the plow body in shifted positionin dotted lines.

The beam of each plow, in accordance with the preferred embodiment ofthe 1nvention, comprises two main bars 1 and 2 which are spaced from oneanother at their rear ends and somewhat farther spaced. apart at theirforward ends. In the construction shown, the main beam bar 1 is'provided between its ends with an Offset or inclined portion 3. A'filler block 4 1s preferably interposed between the inclined por tion 3and the adjacent beam bar 2, and is connected thereto by bolts 5. As setforth in the application above referred to, the

beam bars are coupled at their forward ends to the draft frame to permitthe vertical rise and fall of the plow body connected thereto. Anysuitable coupling may be employed. The coupling shown is similar to theone described and claimed in an application filed by me in theUnitedStates Patent Office March 20, 1912, Serial No. 685,080, and

forth. It is understood, of course, that the main beam bars 1 and 2 arefree to swing vertically upon the horizontal pivot bolt 6 as the plow isworking in the ground, and also to raise and lower the plow from and toworking position.

, The plow body 10 is suitably secured to the lower end of a standard11. The standard is preferably curved, as shown, and 6X tends upwardlyand forwardly from the plow body, the upper portion thereof beingarranged between the rear ends of the main beam bars 1 and 2.' Theforward end of the standard ispivotally connected to the beam bars 1 and2, at a point in front of the rear ends thereof, by a transverse. bolt12. The plow i's provi'ded with a. supplemental beamwhich preferablycomprises a pair of supplemental bars 13, which are arranged outside ofthe rear ends of the main bars 1 and 2 and the forward ends of which arepivotally connected to themain beam bars by the pivot bolt 12. In thepreferred construction shown, the supplemental bars 13 are formed of asingle piece bent to U- shaped form, so that the supplemental beam barsare connected at their rear ends by an integral transverse portion 14.The bolt 12 pivotally connects the plow standard 11 and the supplementalbeam bars 13 to the main beam bars 1 and 2. This bolt also extendsthrough the rear portions of a pair of brackets 15 which overlap theforward ends of plowrstandard. In the preferred form shown, a cast metalblock 18 is secured between the rear ends of the supplemental bars 13 bya pair of transverse bolts 19. A link or bolt 20 extends verticallythrough the block 18 and is fixed adjustably thereto by a pair of nuts21 threaded on the bolt and engaging the upper and lower faces of theblock. The lower end of the bolt is pivotally connected to a bracket 22which is fixed to the lower rear portion of the standard 11 and projectsrearwardly therefrom. The block 18 is provided with a forwardlyprojecting nose or lug 23 which normally rests upon the rear ends of themain beam bars 1 and 2. The rear ends of the main and supplemental beambars are normally connected in rear of the pivoted bolt 12 by a pair ofwooden break pins 24, which extend through registering holes therein.

By adjusting the nuts 21 on the bolt 20, the standard and the plow bodycan be tilted or adjusted about the horizontal pivot bolt 12 in orderthat the plow shall be presented at the proper angle to the ground andso be forced into the ground by the forward movement of the plowingstructure. By tightening the nuts, the standard and plow body arerigidly secured to the supplemental beam bars. To facilitate thisadjustment, the opening in the block 18, through which the bolt 20extends, is preferably slightly conical. By removing the break pins 24,the supplemental beambars 13, standard 12 and plow body 10 can be swungupwardly and forwardly past a vertical dead center position and into theposition shown in dotted lines in Fig. 2; The

parts are supported in this positionby stop 40 shoulders 25 (see Fig. 1)formed upon the brackets 15 and which engage and'arrest the forwardswing of the supplemental 1 beam bars 13. In this position of the parts,the plow body can be readily removed from the standard for sharpening orfor replacing the plow body with a different form, as required fordifferent kinds of work. When the plow body is swung back to normalposition, the stop lug 23 again engages the ends of the main beam bars 1and 2 and the rear ends of the supplemental beam bars are then connectedthereto by the wooden break pins 24:. If the plow body strikes anunyielding obstruction, these pins will break and the plow body andparts connected thereto will be thrown upwardly without injuring any ofthe metal parts of the plow or of its lifting mechanism. After the plowbody has been swung upwardly about the pivot bolt 12 it can be returnedeasily to proper position, since the adjustable connection between thesupplemental beam bars and the plow standard is not disturbed and sincethe return movement of the plow body 65 is arrested in proper positionby the engagement of the nose or lug 23 with the rear ends of the mainbeam bars.

Anysuitable lift mechanismmay be con nected to the main beam bars forraising and lowering'the plow, and the adjustment of the plow forchanging its pitch or angle to the ground, and the manner of mountingthe same to permit it to swing upwardly and forwardly, are independentof any lift mechanism which is connectedto the main beam bars. In theform shown, a standard 26 is pivotally mounted in the lower dependingportions of the brackets 15 and carries a gagewheel 27. Suitable liftingand adjusting mechanism, such, for example, as 0 set forth and claimedin the original application Serial N 0. 629,269 above referred to, canbe connected to the gage wheel standard for raising and lowering theplow and adjusting its working depth. It is obvious that thesupplemental beam bars, the plow standard, and the connections betweenthese parts, and the main beam bars are all independent of the liftmechanism.

Obviously, changesmay be made in the details set forth without departurefrom the essentials of the invention as defined in the claims.
